tls_secret_namedns resource typestls-cert and dns resources. Resource References allow referencing of resources by Resource Type only. In this case, the Resource ID of the resource being provisioned is used.tls-cert and dns resources are associated by having the same Resource ID. In this way, the Resource Definition defining a tls-cert resource could reference the host of the dns resource it should be associated with. An ingress Resource Definition can reference the host of the dns resource and the tls_secret_name from the associated tls-cert. ( ingress resources take the same Resource ID as the dns they are associated with.)
